Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat exchanger capable of appropriately adjusting amounts of heat to be exchanged between three kinds of fluids.SOLUTION: The heat exchanger is configured by arranging at least one tube of refrigerant tubes 16a and cooling water tubes 43a in a stacked manner and includes heat exchange parts 71, 72 configured to exchange heat between at least one of refrigerant tubes 16a and cooling water tubes 43a and air where, in a space formed between neighboring ones of the refrigerant tubes 16a and the cooling water tubes 43a, an air passage 70a through which air flows is formed, as the heat exchange parts 71, 72, the upstream heat exchange part 71 arranged at the upstream side in the airflow direction and the downstream heat exchange part 72 arranged at the downstream side of the upstream heat exchange part 71 in the airflow direction are provided, and the ratio of the number of the refrigerant tubes 16a to the total number of the tubes configuring the upstream heat exchange part 71 is made different from the ratio of the number of the refrigerant tubes 16a to the total number of the tubes configuring the downstream heat exchange part 72.
